lat., which i)reys on Jassids, while fig. 2, 4, 6, 8, show 

 these parts in parasites of Gonatopus-hke appearance, 

 which prev on Fulgoroids, and which are also very simi- 

 lar to one another, but markedly distinct from those above 

 mentioned. The new genera into which 1 have divided 

 the old Gonatopns are easily determined by examination 

 of these chelae, together with the mouth-parts figured on 

 PI. XXXVI, fig. 8-15. 



10. Paradryiinis kochelci, chelae and preceding tarsal joints. 



IT. Ncochclogyniis, chelae and two preceding tarsal joints. 



12. Ncodryiinis kochelci, chelae, and three preceding tarsal 

 joints. 



13. Paraiifcoji iiiyniiccopJiiliis, chelae and three preceding tarsal 

 joints. 



14. . Eiikocbclcia iiiirabilis, chelae. The single lamellate spine at 



the tip of the process of the fifth tarsal joint may be com- 

 pared with that in the same position on the chelae of 

 Tliauinatodryiitus. 



15. Paradryinits kocbclci; pronotum in profile, showing its very 

 irregular outline. 



16. CIdorodryiiius pal/idiis; pronotum with almost regularly 

 convex outline. 



17. Paradryinits: mesonolum showing the parapsidal furrows. 

 i8. CJdorodryiiiiis; mesonotum showing the same. 



19. EchthrodclpJiax; mesonotum showing the same. 



20. Ncochclogymis; mesonotum showing the same. 



All the figures are drawn from female examples. 



PLATE XXXVI II. 



T. Paradryiinis kocbclci, showing the mode of disposition of 

 the long front legs, when at rest. The body is supported 

 on a part of the dorsum of the abdomen, which alone 

 touches the surface on which the creature rests. In the 

 case of the example figured the center of gravity is far 

 in advance of the point of contact between the abdomen 

 and the resting surface, but equilibrium is maintained by 

 the grip of the claws of the middle and hind feet. The 

 legs of the left side only are figured, those on the right 

 side holding similar positions. In dififerent species there 

 is some variation in the positions assumed at rest, but the 

 following genera, A'codryiiuis, Paradrxiiiiis, Chlorodrxinus, 

 TJiaiiinafodryiiiiis, and Chalcogonatopiis. all rest on the re- 

 curved al)domen witli the body subercct, or oblique, and
